The Phrenological Chart

Gall and his followers
identified 37 mental and moral faculties which they thought were represented in the exterior surface of the skull. Gall's initial
list comprised 27 faculties, to which his main collaborator, Spurzheim, added ten more. These faculties were divided
into several spheres: intellectual, perceptiveness, mental energy, moral faculties, love, etc. Most of the faculties
dealt with abstract and hard-to-define personality traits, such as firmness, approbativeness, cautiousness, marvelousness,
eventuality, spirituality, veneration, amativeness. etc. Other phrenological traits have modern scientific counterparts
which can be evaluated with proper psychological tests, such as constructiveness, destructiveness, individuality,
self-esteem, idealism, affection, etc.

The main result of Gall's theory was a kind of chart of the skull, which mapped
the regions where the bumps and depressions related to the 37 faculties could be palpated, measured and diagnosed.
This was a marvelous device for practicioners, and was widely used.
